Engraved steel plates cut up is actually extremely easy and virtually indestructible. You can buy a piece of 100x50x3 mm 316 stainless steel (thats 4"x2"x1/8" in freedom units) for around $5. Engraving it is a simple matter of using a $10 automatic center punch and write the password out in dot punched letters. If necessary, cut plate in N pieces with a hack saw, distribute among N people. I always mark bicycles this way, dot punch my last name underneath the bottom bracket shell. |
